Rebuilding a ku pump so which is the top ring?

The k133 ring set for the ku pump has two top rings in which the dots are installed up. One ring appears to be all steel and the other has some sort of composite bonded to it, which is the top ring? Thank you, Dave

Emglos Model number is not valid??

Model number on tank is WAM5 A-60 and Model number on pump is WAM. Serial number on both tags read 218765. All parts forums do not recognize this model. It is an Emglo from Johnstown Pa.________________The logical place to inquire as to part numbers would be Emglo, George.
